Description

Technical Field

[0001] The utility model relates to the technical field related to tensioners, in particular to a tensioner with a telescopic handle. Background Art

[0002] Most of the existing tensioners are separated from the webbing. When in use, a longer webbing is needed to tie the goods. The two ends of the webbing are fixed by the tensioner, and the webbing is further tightened when the tensioner is engaged, so as to further tighten the goods.

[0003] However, the existing technology also has problems. On the one hand, the webbing and the tensioner are separated, which has low portability. The webbing needs to be fully opened when used. Different goods use different webbing lengths. Often, after the goods are tied tightly, a part of the webbing still needs to be knotted and fixed, resulting in reduced safety. On the other hand, the webbing still needs to be recycled after use, and the operation is very cumbersome. For this reason, those skilled in the art have proposed a telescopic handle tensioner to solve the problems raised in the above background. Utility Model Content

[0004] The purpose of the present invention is to provide a telescopic handle tensioner to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] Telescopic handle tensioner, including:

[0007] A sheet metal base, wherein a central axis is installed in the middle of the sheet metal base;

[0008] A sheet metal handle, comprising a tightening portion and a handle portion, wherein the bottom end of the tightening portion is rotatably connected to the middle portion of the sheet metal base via a central axis, and the top end of the tightening portion is fixedly connected to the bottom end of the handle portion;

[0009] An upper baffle, wherein both side ends of the upper baffle are slidably connected to both sides of the upper portion of the tightening portion, and the bottom end of the upper baffle is symmetrically connected to two downward-facing lower tongues;

[0010] A lower baffle, both side ends of which are slidably connected to both sides of the rear end of the sheet metal base;

[0011] A lower connecting plate, the bottom end of which is rotatably connected to both sides of the rear end of the sheet metal base, and the lower connecting plate can be linked with the lower baffle;

[0012] A retaining spring plate, the bottom end of which is rotatably connected to both sides of the front end of the sheet metal base.

[0013] As a further solution of the present invention: the upper baffle is connected to an extension part at one end close to the handle part, and a first spring is sleeved on the extension part. The inner periphery of the handle part close to the tightening part is connected to a connecting piece, the extension part and the connecting piece are interlaced and matched, and one end of the first spring is against the connecting piece.

[0014] As a further solution of the present invention: a first hole is provided in the middle of the lower baffle, one end of a second spring is installed in the first hole, and the other end of the second spring is connected to the side of the sheet metal base.

[0015] As a further solution of the present invention: a second hole is provided at the rear of the lower baffle, the front top of the lower connecting plate is connected to a front vertical plate that cooperates with the second hole, and the rear top of the lower connecting plate is connected to an upper tongue that cooperates with the lower tongue.

[0016] As a further solution of the present invention: a winding device is installed on the bottom outer wall of the tightening part, gears are installed at both ends of the central axis, and the interior of the winding device is connected to the central axis through a coil spring.

[0017] As a further solution of the present invention: a middle plate is connected to the middle of the top end of the retaining spring plate, and side plates are connected to both sides of the top end of the retaining spring plate.

[0018] As a further solution of the present invention: a protective cover is installed at the front end of the sheet metal base, and the retaining spring plate is arranged on the inner periphery of the protective cover.

[0019] The utility model has the following benefits:

[0020] 1. The tensioner is combined with the webbing. When in use, you only need to pull out an appropriate amount of webbing from the tensioner and fix the head and tail with the hooks on the webbing to fix the tensioner. No extra webbing will be generated, avoiding the safety hazard of the webbing spreading out.

[0021] 2. The opening and closing angle of the sheet metal handle is large enough, the length of the webbing tightened back and forth each time is longer, and it is convenient to tighten with force, which is highly practical. The lower baffle is set at the rear end of the sheet metal base, and the bottom of the lower connecting plate is rotatably connected to the sheet metal base. The lever structure is formed by the lower connecting plate, which can facilitate the lower baffle to be better reset and disengaged, and has high stability in use. BRIEF DESCRIPTION OF THE DRAWINGS
